Sealed Fluid Control Body Installation With Standardized Valve Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid control devices require complex and costly manufacturing processes due to the need for elaborate designs matching specific fluid pipe and casing specifications, leading to increased costs and complicated storage and maintenance, with limited versatility for installation in varying environments.
Innovation Solution
A method for installing a fluid control body in a casing that uses a standardized on-off valve and partition body with a seal component, allowing for installation in a sealed manner without requiring custom designs, and enabling the operation shaft to extend in a direction other than vertical, simplifying the installation process and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fluid control body is designed with an elaborate outer surface shape to closely connect to the casing inner surface, then the sealing performance is improved, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The fluid control body is divided into separate components: a standardized valve body and a separately manufactured partition body. The partition body is designed with a sealing surface that closely connects to the casing inner surface, while the valve body maintains a simple standardized shape. This segmentation allows the sealing function to be achieved without complicating the main valve body manufacturing.
Solution Approach 2:
The sealing function is extracted from the valve body and transferred to the partition body. The partition body is specifically designed with an elaborate outer surface shape that matches the casing inner surface, while the valve body remains a simple standardized component. This extraction resolves the contradiction by assigning the sealing requirement to a dedicated component.
2Reliability
If custom-designed fluid control bodies are manufactured according to specific pipe and casing specifications, then the sealing performance is improved, but the storage and maintenance complexity increases
Solution Approach 1:
The valve body is designed as a standardized component that can be used across different pipe and casing specifications. The partition body is custom-designed to match specific casing inner surfaces. This combination allows the standardized valve body to be universally applicable while the partition body provides the necessary sealing adaptation to specific installations, reducing storage and maintenance complexity.
3Ease of operation
If the operation shaft is extended vertically upward to connect to attachments such as a speed reducer, then the valve control function is improved, but the earth covering space is restricted and installation becomes difficult
Solution Approach 1:
The operation shaft is configured to extend in a direction other than vertically upward (e.g., horizontally or at an angle), changing the dimensional orientation of the control mechanism. This allows attachments such as speed reducers to be positioned in alternative spatial arrangements, reducing restrictions on earth covering space and improving installation versatility in environments with limited vertical clearance.
